Answer:
LiHCO3 its PH >7
Explanation:
the real ph for it is 11.3 so it makes it more than 7
and if you know it is a conjugate base coming from the weak acid H2CO3 so LiHCO3 is a base
<em>Answer:</em>
<em>An Atom can turn into both solid and liquid form depending on the temperature of its surroundings </em>
<em>Explanation:</em>
<em>Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously.
Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states.</em>
Just use q=mCDeltaT
q=energy
m=mass
c=specific heat
Delta T= Change in temperature
Answer:
J (joule) W(watt)
Explanation:
If you're looking for the definition it is
The most common definition of energy is the work that a certain force can do. Energy also cannot be created or destroyed and some examples are
light, heat, mechanical, potential, and kinetic
Answer: CF4
Explanation:
Calculate the molar mass of each compound. Divide the molar mass of Carbon by the molar mass of each compound, then multiply the answer by 100 to get the percentage.
CF4= 12+(19X 4)
=12+76= 88 g/mol
%C= 12/88 x 100= 13.64%
CO2= 12+(16 X 2)
12+32= 44 G/MOL
%C= 12/44 x 100= 27.3%
CH4= 12+ (1 X4)
=12+4
=16 G/MOL
%C= 12/16 X 100= 75%
C204
(12X2) + (16X4)
24+64
= 88 g/mol
%C= 24/88 x 100
= 27.3%
